Signal Routing for a Separate Music and Effects Mix in Surround
When you shift from a stereo project to surround, you need to keep in mind some
minor signal routing consequences. This section discusses what changes you would
make to the submix and output settings. (For information about creating a surround
version of a stereo project, see “
Converting a Stereo Mix to 5.1 Surround
First, assuming that the music and effects are mixed over six surround channels, those
submixes must be routed to the Surround 1-6 output. The Dialogue submix could
either remain routed to the Stereo 1,2 output jacks to be added to the Surround 1-6
mix or routed to the center channel at the submix, or could be panned to the center
channel in a surround signal, as shown below.
To create the surround version of the separate music and effects mix (as described
earlier), you route the Dialogue submix to any output channels other than 1-6. This
example uses channels 7 and 8, the last two available output channels, thus isolating
the dialogue from the music and effects.
